safeclassname

Micro-library for JS that generates a safe CSS classname from a string.

Behaviour

• Spaces are replaced with -.
• Special characters are replaced with _x<charCode> e.g. ! is replaced with _x21.
• If passed undefined or null, safeclassname will return an empty string.

Examples

• safeclassname('Some sentence') - returns "Some-sentence"
• safeclassname('super!') - returns "super_x21"
• safeclassname(undefined) - returns ""
• safeclassname(null) - returns ""
